DIAGNOSIS
Treatment Planning
Glossary of Prosthodontic Terms, Edition 9, J Prosthet Dent 2017;1-105
Treatment plans should be developed to best serve the needs of each individual patient.
According to Boucher 4
developing sequence of procedures planned for the treatment of a patient after diagnosis - Winkler
Name
Must for
Age
The apparent age/biological age of a person is far more important than his actual age and is one of the most significant observations one makes.
In 5th decade onwards :-
No rapid healing.
Tissue not much resilient.
Menopausal hormonal changes make women patients more exacting or hysterical type for esthetics.
Longer learning period because of muscle insufficiency.
Race : disease prevelance
Occupation :influences the degree of importance of factors like esthetics, phonetics & general appearance.
Job & social standing determines the value patient gives on his/her dental health/esthetics.
Address & Telephone no.
The successful prosthodontic treatment depends on both technical skill & patient management according to mental attitude.
According to Dr. MILUS MARYLSON HOUSE (1960)
Philosophic
Exacting
Indifferent Hysterical
Submit to treatment as a last resort, have negative attitude, often poor health, unfounded complaints.
Emotionally unstable, excitable, apprehensive and hypertensive. Unrealistic expectations.(demand equals to natural teeth) Prognosis is often unfavorable.
Additional professional help (psychiatric) is required prior to and during treatment.

•Avoid surgical procedures if possible.
•If not, perform it under proper antibiotics coverage.
•Postpone procedures for at least 6 months if not very necessary.
•Do not treat patient with coronary bypass until at least 2 weeks after operation.
•Always ready with emergency kit & services for an immediate control.
DISEASES OF THE SKIN
Skin diseases like Pemphigus have oral manifestations, which vary, from ulcers to bullae.
Make denture use impossible without medical treatment.
Constant use of the prosthesis should be discouraged for these patients.
Herpes
Use of prosthesis - uncomfortable
Care taken to avoid herpetic whitlow
HYPERTENSION
Oral side effects of antihypertensive medicines
Diuretics - Dry mouth, lichenoid reaction
Beta blockers - Dry mouth, taste changes, lichenoid reaction
ACE inhibitors - Loss of taste, dry mouth, ulceration, angioedema
Calcium channel blockers - Gingival enlargement, dry mouth, altered taste
Alpha blockers - Dry mouth
Direct-acting vasodilators - Facial flushing, possible increased risk of gingival bleeding and infection
Central-acting agents - Dry mouth, taste changes, parotid pain
Angiotensin 2 antagonists- Dry mouth, angioedema, sinusitis, taste loss
Orthostatic hypotension- antihypertensives, antidepressants, centrally acting skeletal muscle relaxants.
Dent Clin N Am 50 (2006) 547–562 Dental Management of Patients with Hypertension.Bruce Bavitz
PROSTHETIC MANAGEMENT
Fabricating a complete denture - avoid causing soft tissue abrasion.
Denture adhesives and artificial saliva may aid in the retention of the prosthesis.
In such patients artificial salivary lubricants should compensate the effect of xerostomia

1. General Appearance
Does the patient appear healthy?
Does the patient show signs of proper nourishment?
Nodules, nevi, ulcerations, enlarged lymph
nodes if any should be noted.
2. Facial Examination
Facial symmetry

Muscle tone
Affects the stability of the denture.
House classified the muscle tone as:
house classification
Greatly impaired muscle tone and function
Usually is coupled with –
NEUROMUSCULAR CONTROL
Enough muscular control to use denture effectively and not to exceed physiologic tolerance of denture bearing tissues by putting excessive pressure on teeth.
Patient chews with great force.
can cause sore mouth as tissue tolerance limit exceeds.
Slight deviation of muscle coordination .
light chewers and can not control dentures effectively.
Lip fullness
Lip length
more exposure of the teeth or sometimes denture base also. Seen in incompetent lip
Equal to one third. Length of lower lip plus chin should be two third.
Lip length
Long
Normal/Medium
Short.
Short upper lip -10-15mm
Medium Lip-16-25mm
Long lip -26-36 mm
Horizontal lip relation (lip step)�

lip
Lip thickness
Thin lips
Thick lips
HEALTH OF THE LIPS
These changes can be caused by
Lip mobility
Patients with minimal lip mobility show very little of the anterior teeth
stroke victims may have paralysis of half the lip, leading to unilateral mouth droop and facial asymmetry
.
LIP SUPPORT
If only tissues around mouth is wrinkled and rest of the face is normal then lack of support is suspected.
- If nasolabial angle is increased after wearing denture --means drooping of lip and loss of lip support occurs.
Palpation of masticatory muscles�
Salivary Glands
salivary glands - bilateral technique.
Mouth Opening
Causes of trismus are: • Trauma
RECOMMENDED SCREENING
EXAMINATION PROCEDURES FOR TMD
1. Measure range of motion of the mandible on opening and right and left laterotrusion. |
2. Palpate for preauricular TMJ tenderness. |
3. Palpate for TMJ crepitus. |
4. Palpate for TMJ clicking. |
5. Palpate for tenderness in the masseter and temporalis muscles. |
6. Note excessive occlusal wear, excessive tooth mobility, fremitus, or migration in the absence of periodontal disease, and soft tissue alterations, for example, buccal mucosal ridging, lateral tongue scalloping. |
7. Inspect symmetry and alignment of the face, jaws, and dental arches. |

SALIVA COLLECTION METHODS
Priya, Y., & Prathibha, M. (2017). Methods of collection of saliva-A Review.International Journal of Oral Health Dentistry; July-September 2017;3(3):149-153
Arch size
Class 1 – Large (best for retention and stability)
Class 2 – Medium (good for retention and stability but not ideal)
Class 3 - Small (difficult to achieve good retention and stability)
Shape
Arch form – House Classification
Class 1 :square
Class 2 :tapering
Class 3 :ovoid
RIDGE CONTOUR�
Maxillary
Class 1- square to generally round
Class 2 - tapering or v-shaped
Class 3 - flat
Ideal is high ridge with flat crest and parallel side – this gives max support and stability
Mandibular
Class 1 : Inverted U- shaped, Parellel walls ,high to medium height with broad crest.
Class 2 : Inverted U-shaped with short flat crest
Class 3 : Unfavourable
or
Inverted w
Short inverted v
Ridge with undercut (results from lingual or buccally placed teeth)
Undercuts
tuberosities.
abrasion of mucosa & pain.
Do not aid in retention and may cause some loss of border seal.
Interarch space
Class 1 - Ideal interarch space to accommodate the artificial teeth (min 16-18mm)
Class 2 - Excessive interarch space
Class 3 - Insufficient interarch space
Interarch space is usually difficult to determine during initial period of diagnosis unless the cast is properly mounted on the articulator, but an early attempt should always be made for proper diagnosis
Examination of inter arch space
Enhances retention and stability (sharry)
CLINICAL SIGNIFICANCE
Ridge parallelism
plane anteriorly.
To observe this relation tell patient to position jaw at VDO and part the lip with finger and mouth mirror or mounted diagnostic cast can be used.
• Denture stability is enhanced by parallel ridge. In Natural dentition the ridges are parallel
• To overcome un-parallelism implant supported denture should be considered.
Ridge relation
The positional relation of the mandibular ridge to the maxillary ridge- GPT.
Maxilla resorbs- upward and inward
Mandible resorbs- downward,
forward, and laterally
Angle classified ridge relationship
THE HARD PALATE
Shape of hard palate can be:
Maxillary tuberosity
Syn : Alveolar Tubercle
It forms the most important area of support as they are less likely to resorb.
Soft palate
Soft palate classification (Winkler)
Palatal sensitivity(gag reflex)
House classification :
Management :
Construct dentures to maximise retention and minimise displacing forces.
Use ’condition’ appliance eg fully extended base for home use.
Psychological assessment if indicated
Palatal throat form
Large and normal in form -immovable band of tissue 5- 12mm distal to line drawn across the distal edge of the tuberosities.
Medium size and normal in form- resilient band of tissues 3-5mm distal to line drawn across the distal edge of the tuberosities.
Accompanies small maxilla. Soft tissues turn down abruptly 3-5mm anterior to the line drawn across the distal edge of the tuberosities.
Lateral throat form
Defined By Neil –Contour of the hard lingual surface of the mandibular ridge in the molar area and the velum like tissue distal to the mylohyoid ridge in the retromylohyoid fossa as it functions under the influence of the tongue
Bounded by
Anteriorly - Mylohyoid
muscle,
Laterally – Pear shaped pad
Posterolaterally – Superior Constrictor Muscle
Posteromedially –
Palatoglossus Muscle
Medially - Tongue
Use a mouth mirror, often the same length and width as a denture flange
-Place it into the lateral throat
area
-Patient is instructed to make some moderate tongue movements
head of the mirror is usually round, and the most common sizes used are the No. 4 Ø (18 mm) and No. 5 (Ø 20 mm)
This form indicates that the anatomical structures will accommodate a fairly long and wide flange
Deep : 0.5 inch space exists between mylohyoid ridge and the floor
Thickness of the border – usually 2-3mm thick
But thicker border of 4-5mm should be used for better seal if the border is flat
Is about half as long and narrow as the class1 and about twice as long as a class3
Moderate : Less than 0.5 inch space exists
Most edentulous mouth have class1 and class2 lateral throat forms,
Shallow : Mylohyoid fold is at the same level as mylohyoid ridge.
Retention is difficult
Tongue Position : Wright classification
Tongue size – House Classification
Class I: Normal in size, development, and function. Sufficient teeth present to maintain normal form and function.
Class II: teeth absent long enough to permit a change in the form and function of the tongue.
Class III: excessively large tongue. Teeth absent for extended period of time- abnormal development of the size of the tongue. Insufficient dentures can lead to development of class 3 tongue.
Tori
Torus palatinus & lingual tori frequently present
Torus palatinus: range from a small prominence in the midline to one that covers the entire hard palate.
Adequate relief must be planned.
Lingual tori: interfere with denture construction & unless very small should be surgically removed.
Class I - Tori absent or minimal in size. Do not interfere with denture construction.
Class II – Moderate size. Mild difficulties in denture construction and use. Surgery not required.
Class III – Large in size. Compromise fabrication & function of dentures. Requires surgical recontouring or removal.
DIGNOSTIC AIDS
tissue which would interfere with the success of new dentures.
